Title: Process and apparatus for the electrostatic separation of oilseed husks
Inventor: ELSPASS ROLF DIPL ING
IPC: B03C1/14
Filed: 1984-06-14
Abstract: The invention relates to a process and an apparatus for carrying out the process for sorting grains, husks and fines from a grain/husk mixture of oilseeds with exploitation of the known corona effect, with simultaneous separation of iron particles possibly contained in a mixture. The aim of the invention is to increase the throughput and to decrease the residual husk content to < 1%. Particles having different conductivity are to be clearly separated by corona discharge after preliminary predrying and fines fractionation. According to the invention, before the oilseed is husked, a moisture potential of 6-15% is produced between husk and grain, then the mixture is fed via a vibrating feed upstream of the roller mid-perpendiculars of a rotating roller having a uniformly fluted surface and a stationary magnet in the interior and is separated with the aid of a corona electrode and an auxiliary electrode into fractions with simultaneous separation of iron particles.

Title: Process for the demodulation of amplitude-modulated input signals with suppressed carrier and circuit arrangement for this
Inventor: HEGELER WILHELM DIPL PHYS
IPC: H03D1/24
Filed: 1984-09-13
Abstract: In the case of a process for the demodulation of amplitude-modulated input signals with suppressed carrier, in which an auxiliary signal essentially at the carrier frequency is generated and synchronised with the input signal, for the purpose of improving the sensitivity of the process in the case of weak input signals, while reducing the amount of circuitry for carrying out the process, the input signal or the auxiliary signal is multiplied by the sign of the low-frequency modulation signal. The modulation signal may be obtained either in analogue form by multiplication of the input signal by the in-phase auxiliary signal and subsequent low-pass filtering or directly in digital form by generation of a digital auxiliary signal and correction of the auxiliary signal, in such a way that it coincides with the input signal with respect to its direct-voltage average value, its amplitude and its phase or frequency. In the latter case, the sign multiplication takes place during the auxiliary signal correction. Circuit arrangements for carrying out the process are specified.

Title: Process for precipitating titanium dioxide hydrate from a titanium sulphate solution by thermal hydrolysis
Inventor: KLEIN EDGAR DR
IPC: C01G23/053
Filed: 1984-10-26
Abstract: In this process, a small amount of a hot alkaline aqueous solution of, for example, NaOH is taken and a small first portion of the titanium sulphate solution is added to it under specified conditions to form a subsolution. This subsolution is then mixed with the rest of the titanium sulphate solution without delay and the titanium dioxide hydrate is precipitated by thermal hydrolysis. It is essential that, in the preparation of the subsolution, at the beginning certain ranges are maintained in the ratio of rate of addition to the amount of TiO2 in the entire titanium sulphate solution. These ranges are determined, in a way which is described in greater detail, using an experimentally determined curve which reflects the dependence of the relative number of nuclei on this ratio. The volume of the first portion of the titanium sulphate solution must be at least large enough for a complete peptisation of the titanium dioxide hydrate initially precipitated to occur while this solution is being added.
